SPRING-SUPPCRT FOR BEDS.

Specification of Letters Patent.

Patented April 17, 1906.

5 gheny and State of Pennsylvania, have invented certain new and useful Improvements in Spring-Supports for Beds, of which the following 1s a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in spring-supports for beds and the invention relates more particularly to a spring-support for folding iron beds.

The invention aims to provide positive and reliable means for holding a woven-wire fabric upon a frame which is connected to the head and foot pieces of a bed, whereby it can be elevated to permit of the head and foot of the bed being folded. To this end I have devised a novel form of casting which serves functionally as a universal joint between the spring-frame and the head and foot pieces of a bed.

In constructing my improved castings I have devised novel meansfor'connecting the woven-wire fabric commonly used with such I castings, said means embodying the frame, which adds rigidity and strength to a completed structure.

A further object of my invention is to provide a folding iron bed which will be eX- tremely simple in construction, strong and durable, comparatively inexpensive, and highly efficient for the purposes for which it is intended.

With the above and other objects in view the invention finally consists in the novel construction, combination, and arrangement of parts to be hereinafter more fully described and then specifically pointed out in the claims, and referring to the drawings accompanying this application like numerals of reference designate corresp ondin parts throughout the several views, in whicI1- Figure 1 is a plan view of a bed constructed in accordance with my invention. Fig. 2 is a plan of the same folded. Fig. 3 is a detail perspective view of one of the rear cornerposts of the bed, illustrating my improved casting in connection therewith. Fig. 4 is a side elevation of another casting used in con nection' with my improved bed. Fig. 5 is a plan view of the same. Fig. 6 is an enlarged detail front elevation of my improved casting, illustrating thev same applied to the post of a bed. Fig. 7 is a vertical sectional view of the same, taken on the line a: 90 of Fig. 6, partly in elevation. Fig. 8 is a rear elevation of the same, and Fig. 9 is a side elevation of another casting used in connection with my improved bed.

In the accompanying drawings I have illustrated a head-piece 1 and a foot-piece 2 of a conventional form of iron bedsteadjthese pieces constituting the four posts 5, 6, 7, and 8 of the bed. My invention resides in the spring-frame which connects these pieces together, forming a strong and rigid structure capable of being folded, whereby it will occupy comparatively small space.

In order that the bed may be folded, I employ special forms of castings which constitute my invention, and by referring to Figs. 6 to 8, inclusive, the main castings will be seen. In order that the bed may be folded to occupy comparatively small space,-.I provide the posts 5 and 6 at the rear of the bed with special forms of castings, which serve functionally as universal joints, ermitting the spring-frame 9 of the bed beingfolded upwardly to a vertical position, as illustrated in Fig. 2 of the drawings, at which time the head and foot pieces 1 and 2' can be folded inwardly against the vertical spring-frame 9. The castings which I use in connection with the osts 5 and 6 and which will be hereinafter called the rear castings are identical in construction. Therefore I only deem it necessary to describe the special construction of the castings in connection with one post. Each of the aforesaid rear castings consists of a two-part sleeve 10, which is adapted to'be clamped upon one of the posts'for instance, the post 6. The two-part sleeve is provided with lugs 11 11, which are secured together by nuts and bolts 12. The one part 14of the casting is provided with an angularly-disposed lug 15, having a circular opening 16 formed therein. Mounted upon the lug 15 is a revoluble member 17, which-consists of a body portion 18, having a depending pin or stud 19, which is adapted to fit in the circular aperture 16 of the lug 15 and revolve therein I at predetermined times. The body portion 18 of the revoluble member 17 is provided with two upwardly-extending pierced flanges 2O 20, which are adapted to receive the I pierced depending lug 21 of a hinged cornerplece 22. A conventional form of nut and bolt 23 is then employed for pivotally connecting the corner-piece 22 to the revoluble member 17. The hinged corner-piece 22 consists of a body portion 24, the one side of which is provided with an angular extension 25, having an oval opening 26 formed therein. The posite face of the body portion 24 is provi ed with an outwardly-extending flange portion 27, which provides a groove 28 in the rear of the body portion 4. The top of the body portion 24 is provided with an upwardlyextending pin or stud 29, the object of which will be presently described.

In connection with my improved bed I employ a conventional form of woven-wire fabric 30, and secured to the ends of this fabric are angle-bars 31 3'1. Metallic strips 32 32 are employed, together with rivets 33 33, for clamping the ends of the woven-wire fabric to the angle-bars 31, this construction being specifically described in connection with my accompanying applications. The ends of the angle-bars 31 and the strips 32 are provided with openings 34 34 to receive the upwardly-extending pin or stud 29 of each of the hinged corner-pieces.

In connection with the posts 7 and 8 at the front of the bed I employ castings hereinafter termed the front castings, one of which is illustrated in Figs. 4 and .5 of the drawings. This casting consists of a two-p art sleeve 35, having an outwardly-extending angular arm 36, which is slotted, as at 37, and this arm and slot forms a socket for the reception of a de ending pin 38, carried by a casting 39, whic is similar in constructionto the body portion 24 heretofore described, with the exception that the pierced depending lug thereof is dispensed with and the depending pin 38 substituted.

In assembling the different parts of my improved bed the sleeves 10 and the members 17 are placed upon their respective posts namely, the posts 5 and 6 at the rear of the bed and the sleeves 35 are placed upon their res ective posts 7 and 8 at the front of the bed The hinged corner-pieces 22 are then pivotally connected by the bolts and nuts 23 to the members 17 The'woven-wire fabric 30 having been connected to the angle-bars 31 31, these bars are placed in engagement with the hinged corner-pieces 22 22 and castings 39 39. This operation is performed by passing the angle-bars downwardly upon the tops of the hinged corner-pieces and the castings, the vertical portions of the angle-bars engaging in the grooves 28 of each casting, while the pins or studs 29 engage in the openings 34 34 of the angle-bars, rigidly holding the angle-bars in engagement with the corner pieces and castings.

. In order to form a rigid framework for the corner-pieces and castings which support the angle-bars and the woven-wire fabric, I employ front and rear rails 40 40, which are oval in cross-section, and these front and rear rails have their ends fitting snugly within the oval tially rectangular frame which is adapted to be supported between the head and foot pieces 1 and 2 of the bed.

When the different parts of my improved bed have been assembled, it will be observed that one side of the spring-frame is movably connected to the posts 5 and 6, while the opposite edge or side of the spring-frame simply rests upon the arms 36 36 of the sleeves 35 of the posts 7 and 8, the depending pins 38 of the castings 39 39 of the bed-spring engaging in the slots 37 37 of the arms 36 36 In order that the bed-spring may be swung upwardly to the vertical position illustrated in Fig. 2 of the drawings, it has been neces sary to provide the slots 37, which permit of the are like movement of the de ending pins 38 38 when the bed-spring ame is swung upwardly. The pivotal connection formed between the corner-pieces 22 and members 17 by the bolts 23 permit of the upward movement of the bed-spring frame. After the frame has been so positioned the head and foot pieces 1 and 2 of the bed can be swung inwardly, as illustrated in Fig. 2 of the drawings, on account of the revoluble connection established between the members 17 17 and the sleeves 10 10 of the posts 5 and 6.

By the construction of my improved bed it will be observed that the same consists of comparatively few parts, to each of which easy access may be had at any time it is desired to disassemble the bed-for instance,

when it is desired to transport or ship the same. The novel form-of castings which I employ permits of the bed being easily and quickly folded.

What I claim, and desire to secure by Let ters Patent, is-

1. In a folding bed, the combination with a head and foot piece, consisting of osts, of sleeves carried by said posts, angul ar arms carried by the front sleeves and having slots formed therein, front corner-castings, revoluble members carried by the rear sleeves, rear corner-pieces pivotally mounted upon the revoluble members, an oval tubular side rail connecting the rear corner-pieces together and another oval tubular rail connecting the front corner-castings together,
